Determining the sequence of events in the formation of stars and planetary systems and
their timescales is essential for understanding those processes, yet establishing ages is …

We present an analysis of the intrinsic colors and temperatures of 5–30 Myr old pre-main-
sequence (pre-MS) stars using the F0-through M9-type members of nearby, negligibly …

We present results of a spectroscopic survey for new K-and M-type members of Scorpius–
Centaurus (Sco–Cen), the nearest OB Association (∼ 100–200 pc). Using an X-ray, proper …

Aims. The SHINE program is a high-contrast near-infrared survey of 600 young, nearby stars
aimed at searching for and characterizing new planetary systems using VLT/SPHERE's …

Young stellar associations hold a star formation record that can persist for millions of years,
revealing the progression of star formation long after the dispersal of the natal cloud. To …

Context. Large surveys with new-generation high-contrast imaging instruments are needed
to derive the frequency and properties of exoplanet populations with separations from~ 5 to …

There is a large change in surface rotation rates of sun-like stars on the pre-main sequence
and early main sequence. Since these stars have dynamo-driven magnetic fields, this …

We reconstructed the star formation history of the Sco-Cen OB association using a novel
high-resolution age map of the region. We developed an approach to produce robust ages …

Medium-resolution integral-field spectrographs (IFS) coupled with adaptive-optics such as
Keck/OSIRIS, VLT/MUSE, or SINFONI are appearing as a new avenue for enhancing the …

Context. Open clusters are recognised as excellent tracers of Galactic thin-disc properties. At
variance with intermediate-age and old open clusters, for which a significant number of …
